I got B+ in Biology 2 and A- in Organic Chemistry Class and Lab

My school's organic chemistry is known as the hardest class. I studied really hard for this class, but I got A- in the lecture and the lab. I am very frustrated because I could have gotten A in the class. For Bio 2, I struggled because the professor was new and tests were extremely difficult. I had to get A in both classes because my science gpa is lower than other competitive applicants. Are these grades good enough? I am planning to ace Ochem 2 and other upper bio classes. Thank you!
